Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The field of invention relates to measuring apparatus, and more particularly pertains to a new and improved horticultural measuring apparatus wherein the same is arranged for convenient and efficient measuring of various plant growths, such as trees and the like.

2. Description of the Prior Art

Measuring equipment of various types for measuring vertical extent of various members has been utilized in the prior art. However such structure has limited application in organization in extensive length, as they have frequently been of a bulky or expansive construction, and typically of a weight limiting their manual manipulation. Examples of the prior art include U.S. Pat. No. 3,492,729 to Crain wherein a measuring rod utilizes extensible pole sections, with locking clamps utilized to maintain each section relative to one another.

U.S. Pat. No. 4,621,431 to Fatool, et al. sets forth a telescoping device utilizing a pin and groove mechanism to maintain alignment and positioning of the sections relative to one another.

U.S. Pat. No. 4,318,228 to Kimura sets forth a pole utilizing elliptical liners to permit extension relative to one another, and spring-type clamps mounted within each of the extensible liners to effect locking relative to one another.

U.S. Pat. No. 4,471,532 to Francis sets forth a graduated measuring rod, including a fixed scale having display windows, with one or more sliding members slidable behind the fixed members and supporting a plurality of sets of sliding members resulting in different sequences of numbers displayed in the windows.

U.S. Pat. No. 3,808,690 to Balder sets forth a further example of a telescoping measuring device utilizing a pivot axis mounted at a lowermost end thereof defined by a "V" shaped frame to permit positioning of the lowermost support rod within a corner portion of a structure.

As such, it may be appreciated that there continues to be a need for a new and improved horticultural measuring apparatus as set forth by the instant invention which addresses both the problems of ease of use as well as effectiveness in construction and in this respect, the present invention substantially fulfills this need.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of measuring apparatus now present in the prior art, the present invention provides a horticultural measuring apparatus wherein the same permits the use of extensible rod members formed of a lightweight and manipulatable organization to permit measuring of various horticultural categories of plants.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 to 6 thereof, a new and improved horticultural measuring apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

FIG. 1 illustrates a prior art measuring rod apparatus 1 utilizing a series of pole members 2 mounted telescopingly and coaxially relative to one another utilizing a clamp structure to maintain the poles in an extended relationship, in a manner as set forth in U.S. Pat. No. 3,492,729.

More specifically, the horticultural measuring apparatus 10 of the instant invention essentially comprises, a base tube 11 telescopingly receiving in a coaxial relationship a first extensible tube 12 within the base tube 11. The first tube 12 in a like manner telescopingly receives a second tube 13, with the second tube 13 telescopingly receiving a third tube 14, with the third tube 14 including a fourth tube 15 telescopingly received therewithin. Each of the tubes are frictionally rotated relative to one another in a desired extended relationship. Further, the tubes are typically formed of a lightweight material of polymeric resin and the like, or other suitable material, to minimize weight in use of the apparatus to enhance manipulation thereof. Further, it is understood that it is desired to typically use five to seven sections, with each section defined as a separate tube. Each of the tubes are coaxially aligned relative to one another, with an external diameter of an upper tube substantially equal to an internal diameter of an underlying tube to promote frictional engagement of the tubes in an extended relationship. Further, the tubes are in four foot sections, each defining gradations of one foot, where it is understood, however, that various gradations may be utilized depending upon the desired length to be measured of an object. The support plate 16, with a socket 17, receives the lowermost end of the base tube 11 therewithin to provide stability to the tube structure to permit its free-standing orientation relative to a tree structure and the like, as illustrated in FIG. 2.

FIG. 3 illustrates the support plate 16 and socket 17, with the socket 17 medially and orthogonally mounted to the top surface of the support plate 16. A series of leg members 18 are orthogonally and fixedly mounted adjacent each corner of the rectangular plate member 16 extending downwardly therefrom, with each leg member 18 defined by a predetermined first diameter. Each leg member includes an inverted conical projection 19 fixedly mounted in a coaxial relationship relative to the leg member at a lower terminal end of each leg member, with the base of each conical projection defined by a second diameter substantially greater than the first diameter to anchor the plate member within the underlying ground support. FIG. 4 illustrates the support plate 16 utilizing a plurality of resilient polymeric inserts 20 that are mounted within the top surface of the support plate arranged parallel relative to one another adjacent opposed end edges of the support plate 16 to permit an individual to provide a friction surface and enable the individual to stand upon the plate member 16, and more particularly upon the inserts to direct the plate member forcefully into the underlying ground support.

FIG. 5 illustrates the plate member 16 employing a "U" shaped handle structure, with a first "U" shaped handle 21 and a second "U" shaped handle 22 provided adjacent the opposed end edges of the plate 16 and projecting orthogonally upwardly from the top surface of the support plate 16 between each insert 20 and an adjacent end edge, as illustrated in FIG. 5. Further, the socket 17 is formed with an "L" shaped slot 24 to receive a lock rod 25 orthogonally and integrally mounted adjacent a lower terminal end of the base tube 11, wherein the lock rod 25 is directed through the "L" shaped slot 24 to fixedly secure the base tube and associated extensible tube structure of the first through fourth tubes 12 through 15 relative to the base plate 16.

As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
